Solution: Count Subarrays With Fixed Bounds

Explore how to count fixed-bound subarrays within an array by applying the two pointers technique. This lesson teaches a linear time method to identify subarrays containing both minK and maxK without invalid elements, improving efficiency over brute-force approaches.

Statement

Given an integer array, nums, and two integers minK and maxK, return the number of fixed-bound subarrays.

A subarray in nums is called a fixed-bound subarray if it satisfies the following conditions:

  1. The smallest value in the subarray equals minK.

  2. The largest value in the subarray equals maxK.

Note: A subarray is a contiguous sequence of elements within an array.
